Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of weaving fabric production technical field, specifically to a winding mechanism of weft knitting machine. BACKGROUND

[0002] Knitted fabric is the fabric formed by bending yarn into loop and interlocking each other using knitting needle. Knitting is divided into weft knitting and warp knitting, and knitted fabric is widely used in garment fabric, garment lining and home textile products. Knitted fabric is generally processed by weft knitting machine or warp knitting machine. The knitted fabric processed by warp knitting machine is sheet-shaped, while the knitted fabric produced by weft knitting machine is cylindrical. Knitted fabric is usually configured with a winding machine for winding during production.

[0003] During winding of knitted fabric, it is generally necessary to humidify and iron the knitted fabric to ensure the quality of the knitted fabric. In the prior art, a winding device of warp knitting machine disclosed in the patent document with publication number CN206616334U humidifies the fabric first and then irons it, so that the wound fabric is flat and wrinkle-free, improving the quality of fabric winding. However, the knitted fabric produced by weft knitting machine is cylindrical in structure and needs to be wound in double layers. In the technical solution, uneven humidification of the knitted fabric may occur during humidification, and the double-layer knitted fabric may be moldy after ironing due to its high humidity. SUMMARY

[0004] The main purpose of the utility model is to provide a winding mechanism of weft knitting machine that can effectively humidify and iron the fabric produced by weft knitting machine, and the ironed fabric can be further dried.

[0005] To achieve the above purpose, the technical solution provided by the utility model is as follows:

[0006] A winding mechanism of a weft knitting machine, comprising two side plates arranged symmetrically in front and back, a conveying roller rotatably connected between the two side plates, two humidifying rollers rotatably connected between the two side plates below the conveying roller, the cloth output from the weft knitting machine passing between the two humidifying rollers after winding around the upper end of the conveying roller, both the humidifying rollers rotating when the cloth moves, a spray pipe in inverted U shape arranged above the two humidifying rollers, the cloth passing between the two longitudinal parts of the spray pipe, the spray pipe being fixed between the two side plates, the two longitudinal parts of the spray pipe being above the two humidifying rollers respectively, a plurality of nozzles being fixedly connected to the lower end of the longitudinal part of the spray pipe, a water inlet pipe being fixedly connected to the straight part of the spray pipe, a first end of a three-way pipe being in communication with the cooling water outlet of the water-cooled main shaft of the weft knitting machine, a second end of the three-way pipe being in communication with the cooling water return pipeline of the water-cooled main shaft, a third end of the three-way pipe being in communication with the water inlet pipe, a filter and a water pump being installed on the water inlet pipe, an ironing assembly being arranged between the two side plates, the ironing assembly being located to the right of the two humidifying rollers, a drying assembly being arranged between the two side plates to the right of the ironing assembly, a guide roller being rotatably arranged between the two side plates to the right of the drying assembly, a winding roller being rotatably arranged between the two side plates above the guide roller, a motor being fixed on any one of the side plates, the output shaft of the motor being connected with the winding roller.

[0007] Specifically, the ironing assembly comprises two ironing units arranged left and right, and the two ironing units are arranged upside down.

[0008] Specifically, the ironing roller of the left ironing unit is above the flattening roller, and the ironing roller of the right ironing unit is below the flattening roller.

[0009] Specifically, the drying assembly comprises two drying units arranged left and right, and the two drying units are arranged upside down, and the drying unit comprises a bellows fixed between the two side plates, a plurality of air outlets are formed on the side of the bellows facing the cloth, and the bellows is fixedly connected with an air pipe on the side away from the cloth, and the air pipe is in communication with the air outlet of the hot air machine.

[0010] Specifically, the bellows of the left drying unit is below the cloth, a plurality of air outlets are formed on the upper end of the bellows on the left side, the bellows of the right drying unit is above the cloth, and a plurality of air outlets are formed on the lower end of the bellows on the right side.

[0011] Specifically, the two humidifying rollers are arranged symmetrically left and right.

[0012] Specifically, the front end of the spray pipe is fixedly connected with the side plate on the front side, and the straight part of the spray pipe is fixedly connected with the side plate on the rear side.

[0013] Specifically, a cooler and a storage tank are installed on the cooling water return pipeline of the water-cooled spindle. A level gauge is installed on the storage tank. The inlet pipe of the storage tank is connected to the water source. A solenoid valve is installed on the inlet pipe of the storage tank. The solenoid valve, the level gauge, and the controller are electrically connected.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. With the symmetrical design of the humidifying rollers, the double-layer fabric can be evenly moistened at the same time. The spray pipe and multiple nozzles accurately spray hot water onto the surface of the humidifying rollers, ensuring consistent water absorption on both sides of the fabric and solving the problem of uneven humidity caused by traditional single-sided humidification.

[0016] 2. The ironing units, which are set up upside down, allow both sides of the fabric to come into contact with independent heat sources and pressure respectively; the ironing rollers have built-in electric heating devices to directly heat the fabric surface and eliminate wrinkles; the flattening rollers apply pressure simultaneously to enhance the flatness of the fabric and prevent the fabric from shifting during roll-up. The independent operation on both sides significantly improves ironing efficiency and roll-up neatness.

[0017] 3. The high-temperature cooling water of the water-cooled spindle is introduced into the humidification system through a three-way valve; the heated cooling water replaces the external hot water source, reducing energy consumption; after the heated cooling water is sprayed onto the fabric, it accelerates the evaporation of moisture in the subsequent ironing process, shortens the drying time, and improves the overall energy efficiency ratio.

[0018] 4. The upper bellows blows hot air downwards, while the lower bellows blows hot air upwards, creating double-sided convection drying; this avoids humidity gradients caused by drying only one side of the fabric, significantly improving drying uniformity and speed.

[0019] 5. The conveyor rollers, humidifying rollers, and ironing rollers are all driven by the movement of the fabric, reducing the motor load and energy consumption. The fabric passes through double-sided humidification, double-sided ironing, and double-sided drying in sequence, and then passes around the guide rollers and is wound up by the take-up roller. The path is compact and there are no folds, which reduces friction damage. The humidification zone, ironing zone, and drying zone are independently controllable to adapt to different process requirements. Attached Figure Description
